SYDNEY s. MCINTYRE, or SEDRO-WOQLLEY, WASHINGTON WINDING ENGINE FRAMEApplication filed June 29,

My invention relates to improvements in winding-engine frames, and hasfor an object to provide a frame of sufficient rigidity for windingengines with the usual base frame thereof omitted.

Hitherto, it has been customary, when making winding or hoisting engineframes, to use a rectangular rigid base frame on to which the sideframes are fastened. My invention avoids this heavy and expensive baseframe.

I attain this and other objects of my improvement with the constructionillustrated in the accompanying sheet of drawing, formusing a part ofthis specification, in which Figure 1 is a plan view of mywinding-engine frame, Fig. 2 is an end elevation of Fig. 1, Fig. 3 is afront side elevation of the central gear-h0using section and Fig. 4 is.an end elevation of Fig. 3.

Similar characters refer to similar parts throughout. Certain parts arebroken away to show other parts hidden thereby.

WVith more particular reference to desig- 2 nated parts: There are twoside frames 5 and 6. Side frame 6 has axle pillow blocks a6 and 66. Sideframe 5 has similar pillow blocks not shown. In the pillow blocks a6 ismounted the drum axle 12 rigidly clamped therein by stud bolts engagedin the pillow blocks extending through axle caps 7 and 11 which aremounted on said axle. In the pillow blocks 66 is mounted the drum axle13 rigidly clamped therein by stud bolts engaged in the pillow blocksand extending through caps 8 and 10 mounted on said axle.

On the foot flange of each side frame are two bosses 14, 14 each havingan opening 15 therein for extending bolts therethrough for fastening theframe to a sled, when used for logging, or to a stationary foundationwhen used for hoisting.

On the interior wall of each side frame is an annular, shift-gearhousing projected toward each other with coinciding axes. On the sideframe 5 is the housing 17 having an interior end flange (117 and gearchamber 017.

On the side frame 6 is the housing 18 havingan interior end flange a18and gear chamber 018. Within flange a18 is a central opening 1931.Serial 110,547,681. 7

7118, and within flange (11.17 is a similar opening not shown. In thetop wall of housing 17 is arr-opening 19 through which a gear mountedonaxle 13may protrude to engage -ashiftgear mounted in said housing. In 5the top wall of housing 18'is an opening 20 through which another gearmounted on said axle 13 may protrude to'be engaged by a shift gear insaid housing. Central, hollow-cylindrical gear housing 21 has end 3flanges 021, (L21 being disposed to bear on end flanges a1? and C618,and holes 16 in flanges a-21 register with holes in flanges a17 and a18through which bolts 23 are extended and .used to firmly clamp theintervening housing '6 -21 tohousings 17 and 18 and thus add anotherbond between side frames 5 and 6 to those provided by axles 12 and 13which are clamped thereon. Thus firmly tied together, side frames 5 and6 have no need for further stability such as would be added by the usualbase frame above referred to.

Centrally disposed in the front wall of housing 21 is neck 24 having anexternal flange'25 andprovided with an opening 26 7 through said wallintocentral gear chamber 22. l f

As illustrated, gear housings 17 and 18 are integral with side frames 5and 6, respectively. This has been the preferred construc- '30 tion inpractice. With central gear housing 21 bolted to and between saidside-frame housings, as illustrated, a stability of frame structure isattained quite suflicient to resist all operative strains without theadded 35 strength of frame provided by the drum axles 12 and 13 clampedthereto. However, with the strength of structure secured through theunion of said side frames, axles U and housing assembly, as shown, anexceptionally strong frame is provided at a relatively reduced costbecause the expensive base frame, referred to, is not required.

In practice this frame construction is used in gasoline winding ordonkey engines where the prime mover speed needs considerable reduction.A. shaft bearing is clamped to flange 25 and the outer end of anextension of the gas-engine shaft is mounted therein n for revolution,and a smaller bevel gear is fastened thereon within housing chamber 22.Bearings are clamped to flanges (117 and (118 and a counter-shaftmounted for revolution therein at right angles to said engine shaft andparallel with axles 12 and 13. A larger bevel gear is fastened on saidcountershaft engaged with said smaller bevel on the engine shaft. Theends of the countershaft in chambers 017 and 018 have splines thereinandon them are mounted shift gears for oscillation and revolutiontherewith. A drum and gear are mounted on axle 13 for revolution, saidgear being extended through opening 20 in housing 18 and engageable bysaid shift gear in the housing 18. A drum and gear are mounted forrevolution on axle'12, said gear being extended through opening 19 inhousing 17 and is engageable by said shift gear therein, saidconstruction providing for the 20 driving of said drums separately orsimultaneus ly at different speeds.

. These gears and drums do not form a part of the frame, which alone isthe subject of this application, and their inclusion in the drawingwould needlessly complicate the same. However, they are referred to inorder that the purposes of this particular reduction to practice of theinvention may be more easily understood.

Having thus disclosed my invention, what I claim as new therein anddesire to secure by Letters Patent is,

A winding engine frame including two side frames, twooppositely-disposed sideframe gear housings one being fastened to theinner wall of each of said side frames, an intervening gear housingbeing fastened to eachof said side-frame gear housings joining the sideframes, and a plurality of drum '10 axles each being clamped'toboth ofsaid side frames joining the same.
